What's mean battery The Fuel Cell (3)? by mary lv

What's mean battery The Fuel Cell (3)? What's mean battery The Fuel Cell (3)? The first practical application of the fuel cell system was made in the 1960s during the Gemini space program, when this power source was favored over nuclear or solar power. The fuel cell, based on the alkaline system, generated electricity and produced the astronauts' drinking water. Commercial application of this power source was prohibitive because of the high cost of materials. In the early 1990s, improvements were made in stack design, which led to increased power densities and reduced platinum loadings at the electrodes. High cost did not hinder Dr. Karl Kordesch, the co-inventor of the alkaline battery, from converting his car to an alkaline fuel cell in the early 1970s. Dr. Kordesch drove the car for many years in Ohio, USA. The hydrogen tank was placed on the roof and the trunk was utilized to store the fuel cell and back-up batteries. According to Dr. Kordesch, there was "enough room for four people and a dog". more info:www.abatteryweb.com
